Brilliant cosmetics

ABSTRACT

The cosmetics of the present invention contain scaly glass flake particles having a smooth metal surface, and the median diameter of the glass flake particles is 10 to 500 μm, and said glass flake particles are contained in 0.1 to 20% by weight with respect to the total amount of the cosmetic composition.

TECHNICAL FIELD

[0001] This invention relates to cosmetics, particularly to cosmeticsfor makeup which realizes a strong glittering feeling and a spatialeffect.

PRIOR ART

[0002] Heretofore, cosmetics including so called pearlescent pigmentsand the like in which metal oxide is coated on a surface have beenprovided as cosmetics for makeup including lip sticks, nail polishes,and eye shadows, and the like (Japanese Unexamined Patent PublicationsS62-187770, H6-116507, H9-132514, H8-302236, and 2000-186012).

[0003] However, with these conventional cosmetics, those with a strongglitter and a spatial effect have not always been provided so far.

[0004] The object of the present invention is to provide cosmetics,particularly, cosmetics for makeup which are capable of manifesting astronger glittering feeling and further, a stronger spatial effect.

DISCLOSURE OF THE INVENTION

[0005] As a result of intensive studies to achieve the above object, theinventors have found that the cosmetics with a strong glittering effectand further, a strong spatial effect can be provided if the cosmeticscomprise scaly glittering particles which have a smooth surface of ametal (with alloys included), that is, a smooth metal surface. Further,the inventors have found that in the present invention, the cosmeticsare preferable which include glass flake particles whose surface iscoated with a metal, inorganic particles whose surface is coated with ametal, metal foil powders, and metal coated resin film powders and thatthe cosmetics which include multi layer film powders are alsopreferable.

[0006] In glittering cosmetics including scaly glittering particles withsuch a metal surface provided, an incident light to the metal surfacereflects on the said smooth metal surface (total refection ispreferable) and as a result of it, the cosmetic coated films having botha strong glittering feeling and a spatial effect in which glitters areinterspersed on the surface of skins, hairs, nails, and the like thathave not been provided in the past can be obtained.

[0007] On the other hand, as an example which is similar but moredifferent from glittering particles whose particle surface is coatedwith a metal, the particles whose surfaces are coated with metal oxideas pearlescent pigments mentioned above are cited. However, in the caseof these glittering particles, metal oxide layers are transparent andthey have a strong tendency to be colored due to the property of metaloxide. Further, the incident light reflects not on the surface of metaloxide, but the light incidents inside the metal oxide layer and isrefracted, and the interference of the light inside the metal oxidelayer occurs, thereby making it difficult to obtain a strong glitteringfeeling and a spatial effect.

[0008] On the other hand, in the case of cosmetics which include scalyglittering particles having a smooth metallic surface, particularly,scaly glass flake particles whose particle surface is coated with ametal, as mentioned above, as a result that the incident light directlyreflects on a smooth metal surface provided on a smooth surface of scalyglass flake particles, a strong glittering feeling and a spatial effectcan be provided by the reflection of the light on this metal surface,and in the case of the cosmetics which include these, particularly inthe case of the cosmetics for makeup, a strong glittering feeling and aspatial effect with a glitter can appear on nails and the like on whichthese cosmetics are coated.

BRIEF EXPLANATION OF DRAWINGS

[0009]FIG. 1 is a schematic sectional view of the cosmetic coated filmsillustrated as a model when the cosmetics of the present invention arecoated on a nail surface.

BEST MODE FOR CARRYING OUT THE INVENTION

[0010] (Glittering particles)

[0011] As glittering particles used in the present invention, it isimportant that they are scaly glittering particles (glittering fragment)having a smooth metal surface. In particular, it is preferable to bescaly glittering particles having a smooth surface on which the incidentlight is reflected totally. Although the said metals are notspecifically limited, metallic simple substance or metallic alloy whoselight reflectance is not less than 0.5 and examples include silver(reflectance; 0.94), aluminum (reflectance; 0.83), gold (reflectance;0.80), nickel (reflectance; 0.63) and the like.

[0012] The said glitter is achieved when scaly glittering particles havesmooth metal surface, however, in the case of the glittering particleswith a small particle diameter of less than 10 μm, a glittering feelingis not enough and it is difficult to obtain a cosmetic coated filmhaving a strong glittering feeling and a spatial effect which have notbeen achieved in the past in which a glitter (glittering fragment) isinterspersed even though the cosmetic coated film can be made to have ametallic luster. Therefore, the size of the particle diameter affectsthis glittering feeling and the median diameter of the said scalyglittering particles is at least 10 μm, at least 25 μm, preferably notless than 30 μm, and more preferably, with a big particle diameter up to500 μm.

[0013] For information, the “median diameter” of the present inventionrepresents the value of D₅₀ (μm) measured by laser diffraction using amedian diameter measuring device under the trade name of “Microtrac HRA9320-X100” manufactured by Leeda & Northlup Co., Ltd.

[0014] According to the present invention, when the cosmetics are coatedon a human nail surface and the like and a cosmetic coated film isformed, in the said coated film, the bigger the value of the mediandiameter of D₅₀ of the glittering particles is, and the smaller themaximum value of the surface roughness (JIS B 0601), R_(max), thestronger glittering feeling appears.

[0015] Consequently, when the minimum value of a glittering feeling towhich both of the property values relate is related as a ratio ofsmoothness to the said median diameter (smoothness (μm)/median diameter(μm) ), particularly when its ratio is not greater than 0.011, aglittering feeling is strongly realized. For information, “smoothness”defined in the present invention is obtained by measuring the maximumvalue of each surface roughness of glittering particles which arepresent per unit area of the surface of a cosmetic coated film in adried state by using the electronic microscope under the trade name of“ERA-8000” manufactured by ELIONIX, thereafter calculating the averagevalue (μm) of these maximum value R_(max).

[0016] For information, in the embodiment of the present invention,glittering particles can be used for cosmetics including facialcosmetics, makeup cosmetics hair cosmetic materials, and the like,particularly they can preferably be used for nail polishes, pedicures,nail polishes, mascaras, eyeliners, eye shadows, lipsticks, cheeks,foundations, or the like without limited to aqueous or oily, regardlessof being in solid or in liquid.

[0017] In liquid, it is preferable that the cosmetics havepseudo-plasticity fluidity (thixotropic property). With this property,settling can be prevented and the aggregated gathering of scalyglittering particles can be prevented even when scaly glitteringparticles with a big particle diameter are included, and when the saidcosmetics are coated, a cosmetic coated film can be obtained with thesaid glitter interspersed which have not been realized in the past.

[0018] When colorants are included in the cosmetics, the glitteringparticles of the present invention is preferably the ones in which thecoating ratio of the colorants is not greater than 80%. Here, the“coating ratio of the colorants” shows the coating ratio of thecolorants which include coloring pigments and the like covering thesurface of a particle and is represented by a coating area of thecolorant to the total superficial area of a particle surface. In thepresent invention, in a surface of cosmetic coated film, as forplurality of glittering particles per unit area, by making digitalimages taken by a polarization microscope “OPTIPHOT” manufactured byNikon Corporation and a digital camera “HC-300Z” manufactured by FujiPhoto Film Co., Ltd binary with an image processing software “ImagePlus” manufactured by Horie-MS, the superficial area of the saidparticles and the coating area of the colorants are measured, and thecoating ratio is calculated taking the average value. This “coatingratio of the colorants” is the property value that can be adjusted bythe size of glittering particles and of colorants, amount to becontained, and dispersibility in the cosmetics of each particle as wellas viscosity of cosmetics or the like.

[0019] In the present invention, as base particles of glitteringparticles, as mentioned above, glass flake particles, inorganicparticles, metal foil powders, metal coated resin film powders, multilayer film powders and the like can be cited. In other words, in thepresent invention, scaly glittering particles having a smooth metalsurface have the structure in which the said base particles are coatedwith a metal. Here, although “coating” not only includes the total ofthe particle surface, but also includes a part of the particle surface,glittering particles whose total particle surface is coated with a metalare preferable. This similarly applies not only to glass flakeparticles, but also to particles with other metal coating structurehereinafter.

[0020] To cite one example as glass flake particles whose particlesurface is coated with a metal, glass flake particles coated with ametal by an electronless plating method can be used. Examples includeglass flake particles coated with silver under the trade names of“METASHINE REFSX-2015PS”, “METASHINE REFSX-2025PS”, “METASHINEREFSX-2040PS” manufactured by TOYO ALUMINIUM K. K. and “METASHINERCFSX-5480PS”, “METASHINE RCFSX-5230PS”, “METASHINE RCFSX-5150PS”, and“METASHINE RCFSX-5090PS” manufactured by Nippon Sheet Glass Co., Ltd.

[0021] In addition, glass flake particles whose surface is coated with ametal of flaky glasses by a sputtering method can also be used. Examplesinclude glittering particles coated with silver under the trade names of“CHRYSTAL COLOR-GF2125”, “CHRYSTAL COLOR-GF2125-M”, “CHRYSTALCOLOR-GF2140”, and “CHRYSTAL COLOR-GF2140-M” manufactured by TOYOALUMINIUM K. K. Further, the examples of the particles whose surface iscoated with nickel- chrome-molybdenum alloy include the productsmanufactured by TOYO ALUMINIUM K. K. under the trade names of “CHRYSTALCOLOR-GF2525”, “CHRYSTAL COLOR-GF2525 M”, “CHRYSTAL COLOR-GF2540”, and“CHRYSTAL COLOR-GF2540 M”. Other examples include “CHRYSTAL COLOR-GF250”manufactured by TOYO ALUMINIUM K.K. coated with brass, “CHRYSTALCOLOR-GF1345” manufactured by TOYO ALUMINIUM K. K. coated with silveralloy, and “CHRYSTAL COLOR-GF1445” manufactured by TOYO ALUMINIUM K. K.coated with titanium.

[0022] The median diameter of the glass flake particles of the presentinvention whose particle surface is covered with a metal is preferablynot greater than 500 μm, and particularly 10 to 500 μm. When the mediandiameter exceeds 500 μm, slippage occurs at the time of coating and thefinish is not preferable. For information, when the cosmetics of thepresent invention are filled in a ball-point pen type cosmetic containerand is coated on a surface of a human skin or nail surface with therotation of a ball at the tip, the median diameter of glitteringparticles is preferably set not greater than 100 μm from the viewpointof fluidity.

[0023] The said glass flake particles in the present invention arepreferably contained in 0.1 to 20% by weight with respect to the totalamount of the cosmetic composition. When the glass flake particles arecontained in less than 0.1% by weight, a glittering feeling and aspatial effect are not satisfactory. On the other hand, when the saidglass flake particles exceed 20% by weight with respect to the totalamount of the cosmetic composition, the solid contents become too muchand the finish of the cosmetic coated film is not beautiful and theusability deteriorates, too. The optimum content of the glass flakeparticles is 0.5 to 10% by weight.

[0024] For information, the said glass flake particles in the presentinvention can be used alone or in combinations of two or more of them.Further, the said glass flake particles can be used by mixing with glassflake particles with the particle surface of metal oxide provided, withthe metal coated inorganic particles mentioned hereinafter, and withglittering pigments including aluminum pigments or pearlescent pigments,or the like.

[0025] (Inorganic particles)

[0026] The inorganic particles used in the present invention areinorganic particles having a smooth metal surface (excluding glass flakeparticles). The examples include inorganic particles coated with a metalby metal deposition or the like. To be specific, mica-like iron oxide(III) whose surface is coated with aluminum-manganese can be used.Examples include the trade names “Paliocrom Copper L 3000” and“Paliocrom Copper L 3001” manufactured by BASF Ltd.

[0027] The median diameter of inorganic particles having the said smoothmetal surface is not greater than 500 μm, preferably 10 to 500 μm as themedian diameter of the said glass flake particles. When the mediandiameter of the metal coated inorganic particles exceeds 500 μm, theslippage occurs at the time of coating and the finishing state is notpreferable.

[0028] In addition, even in the case of aluminum pigments, as statedabove, when the scaly aluminum powders having a median diameter of atleast 10 μm and having a smooth surface, preferably, the scaly aluminumpowders having the ratio of the said smoothness is not greater than0.011 are used, the twinkling glitter which the said particlesinherently have can be realized in a coated film. Examples of suchaluminum powders capable of providing these property values include thetrade names “WXM U 75 C” (median diameter: 13 μm) , “WXM 5422” (mediandiameter: 18 μm), “WXM 1440” (median diameter: 30 μm), “WXM 1415”(median diameter: 50 μm) manufactured by TOYO ALUMINIUM K. K.Particularly, in the case of aluminum powders, trade names “WXM 1440”(median diameter: 30 μm) and “WXM 1415” (median diameter: 50 μm)manufactured by TOYO ALUMINIUM K. K. can preferably be used.

[0029] Particularly, in the case of aluminum powders, the trade names“WXM 1440” (median diameter: 30 μm) and “WXM 1415” (median diameter: 50μm) manufactured by the above manufacturer whose particle mediandiameter is not less than 30 μm, that is, over 25 μm can preferably beused.

[0030] The said inorganic particles are, as the said glass flakeparticles, preferably contained in 0.1 to 20% by weight with respect tothe total amount of the cosmetic composition. When the said inorganicparticles is contained in less than 0.1% by weight with respect to thetotal amount of the cosmetic composition, the glittering feeling is notenough, and when the content of the inorganic particles exceeds 20% byweight with respect to the total amount of the cosmetic composition, thesolid contents become too much, the finish is not beautiful and theusability deteriorates. The optimum amount of the said inorganicparticles to be contained is 0.1 to 10% by weight.

[0031] For information, the said inorganic particles having a smoothmetal surface can be used alone or in combinations of two or more ofthem. In addition, the said inorganic particles can be used not onlywith glass flake particles whose particle surface is covered with ametal but also with glittering pigments including aluminum pigments andpearlescent pigments in mixture.

[0032] (Metal foil powders)

[0033] The metal foil powders used in the present invention are definedas general terms for metallic powders in which the metal foils includingaluminum foils are grounded. Therefore, in the present invention, metalfoil powders with such definition can be used. However, in the case ofglittering cosmetics which contain the aluminum foil powders, whose foilsurface is processed by mirror surface treatment, and in particular, inthe case where the flakes are block-type, when used for make up, it ispreferable in that a stronger glittering feeling and a spatial effectcan be provided. In addition, in the case of aluminum foil powderscolored by pigments or dyes as well as whose surface is processed withmirror surface treatment, such a make up can be obtained with a strongglittering feeling and a spatial effect having the color tone that hasnot been realized in the past, according to the hue colored by pigmentsand dyes.

[0036] Although the granularity of this metal foil powders is notspecifically limited, the granularity of 500 mesh to 50 mesh ispreferable. When the granularity exceeds 500 mesh, the glitteringfeeling is inferior since flake particles are too small. The granularitywith less than 50 mesh can still be used, however, it is preferable thatthe granularity is not less than 50 mesh to be contained in cosmetics.

[0037] The metal foil powder of the present invention is preferablycontained in 0.01 to 20.0% by weight with respect to the total amount ofthe cosmetic composition. When the said metal foil powders are containedin less than 0.01% by weight, a glittering feeling and a spatial effectare not enough. When the said metal foil powders exceed 20.0% by weight,the solid contents become too much, the finish is not beautiful, and theusability deteriorates. The optimal amount to be contained is 0.05to10.0% by weight. In addition, the said metal foil powders in the presentinvention can be used with the said metal coated inorganic particles,glass flake particles whose particle surface is coated with a metal, andwith glittering pigments such as aluminum pigments, pearlescent pigmentsor the like in mixture.

[0038] (Metal coated resin film powders)

[0039] The metal coated resin film powders used in the present inventionare composed of resin film powders coated with metals including aluminumby deposition, and the like. For example, resin film powders ofpolyethylene terephthalate (PET), with aluminum deposited thereon orcolored resin film powders can be cited. In addition, by using a pressdie of hologram, resin film powders (aluminum deposited PET embosshologram) in which aluminum is deposited on polyethylene terephthalate(PET) with invisible fine grooves embossed can be used. This PETembossed hologram glitters in rainbow colors, realizing a glitteringfeeling by a prism effect.

[0040] To be specific, examples including the trade names “DIAMOND PIECE(regular type) series Silver, part number 55, DG Gold, , the same partnumber, LG Gold, the same part number, and Green, part number 501, Blue,the same part number, Red, the same part number, Maroon, the same partnumber, and Black, the same part number manufactured by DAIYA KOGYO CO.,LTD can be cited. Also, part numbers HG-5EP and HG-S20 of “DAIYAHOLOGRAM” series manufactured by DAIYA KOGYO CO., LTD can be cited.

[0041] The granularity of this metal coated resin film powders is notspecifically limited, but the granularity of 140 mesh to 50 mesh ispreferable. When the granularity exceeds 140 mesh, flake particlesbecome too small and the glittering feeling is inferior.

[0042] The metal coated resin film powders are preferably contained in0.01 to 20.0% by weight with respect to the total amount of the cosmeticcomposition. When the said metal coated resin film powders is containedin less than 0.01% by weight with respect to the total amount of thecosmetic composition, a glittering feeling and a spatial effect are notenough. When the content of the metal coated resin film powders exceed20.0% by weight with respect to the total amount of the cosmeticcomposition, the solid contents become too much, the finish is notbeautiful, and the usability deteriorates. The optimal amount of themetal coated resin film powders to be contained is 0.05 to 10.0% byweight. In addition, the said metal coated resin film powders can beused with the said metal foil powders, the said metal coated inorganicparticles, glass flake particles on whose particle surface metal ormetal oxide is coated and with glittering pigments including aluminumpigments, pearlescent pigments, or the like in mixture.

[0043] (Multi layer film powders)

[0044] The multi layer film powders in the present invention refer tothe fine powders of the multi layer films and the synthetic resin filmpowders in which colors change depending on the viewing angles due tothe color development of multi layer with the refraction of light. This“multi layer film powders” include multi layer film powders colored withhigh transparency.

[0045] The multi layer film powders are not specifically limited so longas they are color materials capable of developing color of a glitteryfeeling by having a mode of a multi layer film. Such multi layer filmpowders include “Crystal color” series and “Rainbow flake” seriesmanufactured by DAIYA KOGYO CO., LTD, and the like.

[0046] Examples of the said “crystal color” series include part numbers“X-5”, “X-20”, “X-40”, “X-701-30”, “X-701-10” and in each of the partnumbers, there are color tones including opal, topaz, blue topaz,emerald, coral, sapphire, diamond, aqua marine, peridot, and blue moon.In other words, series of “crystal color X-20” include trade names“crystal color X-20 OPAL”, “crystal color X-20 TOPAZ”, “crystal colorX-20 BLUE TOPAZ”, “crystal color X-20 EMERALD”, “crystal color X-20CORAL”, “crystal color X-20 SAPHIRE”, “crystal color X-20 DIAMOND”,“crystal color X-20 AQUA MARINE”, “crystal color X-20 PERIDOT”, and“crystal color X-20 BLUE MOON”.

[0048] The multi layer film powders are preferably contained in 0.01 to20% by weight with respect to the total amount of the cosmeticcomposition. When the glass flake particles are contained in less than0.01% by weight with respect to the total amount of the cosmeticcomposition, a glittering feeling and a spatial effect are notsatisfactory. On the other hand, when the multi layer film powdersexceed 20% by weight with respect to the total amount of the cosmeticcomposition, the solid contents become too much, the finish is notbeautiful and the usability deteriorates. The optimum content of themulti layer film powders is 0.05 to 10% by weight. In addition, the saidmulti layer film powders can be used with the said metal coated resinfilm powders, the said metal foil powders, the said metal coatedinorganic particles, glass flake particles whose particle surface iscoated with a metal, and with glittering pigments including aluminumpigments, pearlescent pigments, or the like in mixture. For information,the granularity of the multi layer film powders is preferably 40 mesh to200 mesh.

[0049] In the cosmetics of the present invention, various componentsused as ordinary cosmetics, particularly cosmetics for make up canappropriately be selected and used in so far as they do not inhibit theeffect of the present invention. These components include colorants(coloring matter including pigments, dyes, or the like), oily componentsincluding solid oils, semi solid oils, liquid oils, or the like,further, organic solvents, moisturizing agents, resins, thickeningagents, waxes and oils, plasticizers, ultra violet ray absorbing agents,anti oxidants, antiseptics, disinfectants, surfactants, perfumematerials, water, powdery materials, pH modifiers, water solublepolymers, beauty components, and the like.

[0050] Examples of oily components include high aliphatic alcohols, highaliphatic acids, ester oils, paraffin oils, waxes, and the like.Examples of organic solvents include alcohols such as ethyl alcohols,propylene glycols, sorbitols, glucoses, and the like, as well as ethylacetate, acetone, and toluene. Examples of moisturizing agents includemuco polysaccharids, collagens, PCA salts, lactate, and the like. And asfor surfactants, various kinds of surfactants can be used includingnonionic types, cationic types, anionic types, and ampholyte types.Further, examples of thickening agents include pullulan, xanthan gum,welan gum, rhamsan gum, succinoglucan, dextran, tragacannth gum, guargum, tara gum, locust bean gum, ghatti gum, arabinogalactan gum, gumarabic, quince seed gum, pectin, starch, psyllium seed gum, pectin,carageenan, alginic acid, agar, gelatin, casein, albumin, polyvinylpyrrolidone, ethyl cellulose, carboxy methyl cellulose, carboxy vinylpolymer, N-vinyl acetamide type resins. As for these thickening agents,those capable of providing pseudo plasticity fluidity (thixotropicproperty) are included.

[0051] As for colorants, various kinds of dyes can be used which areusually compounded in cosmetics including C.I Acid red 27 (Red No.2),C.I Acid red 51 (Red No.3), C.I Acid red 18 (Red No.102), C.I Acid red28 (Red No.104), C.I Acid red 94 (Red No.105), C.I Acid red 52 (RedNo.106), C.I Acid yellow 23 (Yellow No.4), C.I Acid yellow 3 (YellowNo.5), C.1 Food green 3 (Green No.3), C.I Food blue 2 (Blue No.1), C.IAcid blue 74 (Blue No.2), and the like as well as various kinds ofpigments (coloring pigments and/or body filler pigments), includinginorganic pigments such as titanium oxide, graphite, colcothar, carbonblack, ultramarine blue pigment, kaolin, aluminum oxide, magnesiumcarbonate, calcium carbonate, and organic pigments such as C.I. pigmentblack 1 (Black No401) C.I. pigment green 7, C.I. pigment blue 15 (BlueNo4), C.I. pigment red 112, C.I pigment violet 19, Watching red, C.I.pigment 57-l(Red No201), C.I. pigment 57 (Red No202), and various kindsof other pigments which are usually compounded such as organic tarpigments, lake pigments with organic coloring mater, and the like.

[0052] The production method of the cosmetics of the present inventionis obtained by mixing each component as mentioned above. Upon mixture, aknown method on each kind of cosmetics can be adopted. The mode of thecosmetics of the present invention can be various including stick types,powder types, liquid types, emulsion types, gelling types, cake types,cream types, pencil types, and the like. Stick types are preferable whencoating on cheeks or lips, for example, which can be obtained bysolidification with waxes contained. Powder types are preferable whencoating on cheeks as rouge compositions, for example, which can beobtained by involving inorganic fillers such as kaolin, aluminum oxide,magnesium carbonate, calcium carbonate, and the like. The mode of theabove cosmetics is the one that can be obtained by involving a knowncarrier component. In addition, the cosmetics can be used as the ones oftransfer types which are transferred to the skin, or the like.

[0053] Further, the cosmetics of the present invention can be applied toball point pen type applicators (ball point pen type containers) with aball retained in a pen tip, and the cosmetics filled in the container,which are coated on skins, nail surfaces, or the like with the rotationof a ball.

[0054] In this case, in the reservoir of the container, liquid cosmeticsor semi liquid cosmetics such as moisturizers and the like can befilled. However, by involving the said thickening agents which providepseudo plasticity fluidity (thixotropic property), it is also possibleto apply to the ball point pen type applicators (ball point pen typecontainers) which have never been in the past in which the cosmetics arecoated on skins, nail surfaces, and the like with the sudden lowering ofthe viscosity due to a shear force acting on the cosmetics although theyare gel type (non-flow or hard to flow) cosmetics when they arecontained in the said applicators.

[0055] The cosmetics of the present invention can also be applied notonly to the ball pen tip, but also to the pen type applicators (pen typecontainers) comprising fiber bundles, or the like. The cosmetics of thepresent invention can not only applied to the provision structure of thedirect liquid type, but also be applied to the inner lead type in whichthe cosmetics are impregnated in the inner lead of fiber bundles or thelike or the bulb type applicators (pen type containers) in which thecosmetics are provided to the pen lead via a bulb. However, in the caseof pen type applicators (pen type containers) in which scaly glitteringparticles with a smooth metal surface and the large particle diameter ofat least 10 μm, particularly not less than 30 μm are contained in thecosmetics, it is preferable to apply to the containers in whichcosmetics with pseudo plasticity fluidity (thixotropic property)provided, particularly, to the ball pen type applicators (ball point pentype containers). No doubt, the present application can be applied tothe liquid or semi liquid type cosmetics with Newtonian fluidityproperty.

[0056] When the mode of the present invention is aqueous, it ispreferable to use synthetic resin emulsion with acrylic types,styrene-acrylic types, vinyl acetate types, and the like.

[0057] In the present invention, since the dimension of glitteringparticles is large, it is sometimes difficult to fix the base particlesof glittering particles and the like firmly on the coated films, theglittering particles are easily peeled due to rubbing or the like aftercoating, and sometimes the generation of a strong glittering feeling anda spatial effect on cosmetic coated films are hard to be realized withthe low durability of cosmetic coated film having a glittering feelingand a spatial effect. From the above, when cosmetics include scalyglittering particles having a large particle diameter and a smooth metalsurface, particularly, the said glass flake particles, it is desirableto include binder components which fix the said glittering particles ona coated films.

[0058] (Forming method of cosmetic coated films and coated films)

[0059] Although the forming method of the cosmetic coated films of thepresent invention is not specifically limited, it is desirable that thescaly glittering particles having the median diameter of at least 10 μmand having a smooth metal surface are scattered and interspersed in thecosmetic coated films. In particular, in utilizing cosmetics whichinclude colorants(coloring pigments), such method is preferable that thescaly glittering particles are distributed with the ratio of not greaterthan 80% to the coated films as a whole and the said colorant particlesare distributed between the said glittering particles.

[0060]FIG. 1 is a schematic sectional view of a cosmetic coated filmillustrated as a model when the cosmetics of the present invention arecoated with the above method. As shown in FIG. 1, in the presentembodiment, the said glittering particles 101 are distributed on thesurface of nail 2 (coated surface) to nail surface 10 as a whole withthe distribution ratio of not greater than 80%, and coated film 1 can beformed in which colorant particles 103 are distributed betweenglittering particles 101 and glittering particles 102. Detailedexplanation according to the present embodiment goes that, in thiscoated film 1, the said glittering particles 101 and 102 are, from themicroscopic view point, deposed on the surface of nail 2 (coatedsurface) maintaining the smooth surface to the uneven surface whichcomposes the said surface and further, between glittering particles 101having this smooth surface and glittering particles 102 having a smoothsurface, coloring particles 103 are distributed as particle groups ofthe colorant. In the embodiment of the present invention, two glitteringparticles 101 and 102 show coated films, however, they are naturallyplural of glittering particles and it is important that it is a coatedfilm between which the said glittering particles, and the colorants aredistributed and the particle groups of the colorants are deposed. Byadopting such a forming method of a coated film, in glitteringparticles, with the presence of an uneven surface which composes thesurface of nail 2 (coated surface), plural of smooth surfaces withvarious angles are interspersed on the surface of a coated film andsince these glittering particles are preferably scaly glitteringparticles in which the coating ratio of the colorants covering thesurface of the said particles is not greater than 80% in a state of adried coated film, the incidence of a light to the particles of thecolorants covering the surface of particles 101 and 102 are none or verylittle, and the reflected light to each of the smooth surfaces ofglittering particles are not disturbed and incidence 31 and reflection32 of light 3 are obtained according to the smooth surface of glitteringparticles. Further, as shown in FIG. 1, for example, since incidence 31and reflection 32 of light 3 with different angles to smooth surfacesill and 112 occur, a twinkling glitter is realized since the viewingangle of the coated films subtly changes.

[0061] Further, in the present embodiment, since the glitteringparticles having the said property value are distributed with thedistributing ratio of preferably not greater than 80% to the coated filmsurface as a whole and since the coated film is in such a way thatbetween the glittering particles coloring particles are distributed, thecolor development is maintained in good balance, providing a twinklingglitter and a color development each other synergistically, therebycapable of providing colored glittering feeling to a coated film. Forinformation, when the said glittering particles are distributed with adistributing ratio of over 80% to the coated film as a whole on the nailsurface (coated surface), even though the colorants are present betweenthe plurality of glittering particles, a glittering feeling ofglittering particles overcomes the color development of coloringparticles on the surface of a coated film, which inhibits colordevelopment of the said colorants. Moreover, a visual glittering feelingof glittering particles appearing on a surface of a coated film is notdecided solely by an area occupied by glittering particles on a surfaceof a coated film, but rather, by contrast, a glittering feelingdeteriorates since the colored surface of glittering particles arecomposed together with the lowering of color development of colorantparticles when glittering particles occupy most of the coated filmsurface. In other words, since a glittering feeling of glitteringparticles is a visual perception given off synergistically in relationto distribution of colorants which are present among glitteringparticles, it is preferable that this glittering feeling is distributedwith the distribution ratio of not greater than 80% to a whole coatedsurface in relation to distribution of colorants. For information, the“distributing ratio” of glittering particles in the present invention isa numerical value (%) obtained by making the digital image taken by apolarization microscope “OPTIPHOT” manufactured by Nikon Corporation anda digital camera “HC-300Z” manufactured by Fuji Photo Film Co., Ltdbinary by an image processing software “Image Plus” manufactured byHorie-MS, measuring the area of glittering particles to the total areaof a coated film, thereby calculating the ratio. Here, it is furtherpreferable that the scaly glittering particles of the present inventionare made to be particle sin which the coating ratio of colorants whichcover the surface of the said particles is not greater than 40% in astate of a dried coated film. Further, it is the most suitable that thedistribution ratio of these scaly glittering particle sis between therange of 20 to 45% with respect to the total area of a coated film.
